The cotton-top tamarin is a small species of monkey - known for the shock of long white hair that flows over its head. These unique looking creatures spend their time in the tree-tops of forests from Costa Rica to Columbia. Despite their remote locations, the effects of the modern world are threatening their existence – with deforestation stealing 75 percent of their natural habitat. Sadly, it’s estimated that today there are only about 2000 cotton-top tamarins left in the world.
